[分享]FRED如何调用Matlab [复制链接]

简介：FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图，本文的目的是通过运行一个案例来实现与Matlab的相互调用，在此我们需要借助脚本来完成，此脚本为视为通用型脚本。 opKtSF|)  
<Fi/!  
配置：在执行调用之前，我们需要在Matlab命令行窗口输入如下命令： &@yW<<  
enableservice('AutomationServer', true) E$gcd#rT  
enableservice('AutomationServer') 3vx?x39*Y  
_95V"h
 
结果输出为1，这种操作方式保证了当前的Matlab实体可以用于通信。 I<DS

在winwrp界面，为增加和使用Matlab类型的目录库，我们需要如下步骤： <S<(wFE@4  
1. 在FRED脚本编辑界面找到参考. $%LjIeVA5  
2. 找到Matlab Automation Server Type Library CQS34&G$a  
3. 将名字改为MLAPP o}<}zTU

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix，PutWorkspaceData适用于存储一般的数据在工作区，并赋予其为变量，PutFullMatrix试用于复数数据。 e tY9Pq

现在将脚本代码公布如下，此脚本执行如下几个步骤： vV8}>  
1. 创建Matlab服务器。 MbYAK-l.h  
2. 移动探测面对于前一聚焦面的位置。 m3,i{  
3. 在探测面追迹光线 -[Q%Vv!8  
4. 在探测面计算照度 RV-
7y^[]^  
5. 使用PutWorkspaceData发送照度数据到Matlab ~b*f2UVs  
6. 使用PutFullMatrix发送标量场数据到Matlab中 +h"RXwlBM  
7. 用Matlab画出照度数据 |:C=j/f   
8. 在Matlab计算照度平均值 ,u/GA<'#M  
9. 返回数据到FRED中 El,p}Bi.
